Patent GB-422302-A (GB)
Title: Improvements in the manufacture and production of lacquers from cellulose esters
IPC: C09D101/18
Filed: 1933-12-20
Abstract: Black cellulose ester lacquers are obtained by colouring cellulose ester lacquers with black pigments which have been subjected to treatment with soluble dyestuffs in a condition to be adsorbed on the surface of the pigments.  This is effected by pretreating the soluble compounds with oleic acid or dibutyl phthalate at elevated temperatures and working up the soluble dyes and pigments mechanically or by heating under pressure. Nitrocellulose softening agents or solvents are advantageously used.  For example nitrocellulose is kneaded with a softening agent in alcohol and a solution of the dye added and the mixture rolled until solvents cease to remove the soluble dyes from the mixture.  According to an example, black dye solutions are made up of Indulin base with oleic acid in solvent naphtha.  Nigrosine base with the same ingredients, or bone pitch with oleic acid and dibutyl phthalate.  The dyestuff mass is prepared by mixing one of the pretreated dye solutions with nitrocellulose, carbon black, dibutyl phthalate and ethyl alcohol and working up on the rollers. The lacquer is finally prepared by mixing more nitrocellulose with ester resin, dammar resin, a mixture of toluene and xylene, butyl acetate, ethyl acetate, butanol, blown castor oil, and dibutyl phthalate and incorporating the prepared pigments.  The Specification as open to inspection under Sect. 91 refers also to the use of soluble acidreacting compounds, esters &c. in particular, oil acids, stearic, naphthenic and phthalic acids as pretreating agents for the soluble dyes.  This subject-matter does not appear in the Specification as accepted.

Title: Programmable automatic controller
IPC: C03B7/00
Filed: 1974-08-19
Abstract: 1482117 Automatic control BALL CORP 19 Aug 1974 [19 Oct 1973] 36347/74 Heading G3N A programmable automatic controller for at least one machine provides facilities whereby component actuating times, in a cycle of machine operation, can be selectively varied while the machine is operating.  As shown, Fig. 1, a pulse generator 11 provides a train of pulses which are provided (a) as a set number during a machine cycle or (b) to denote a time base within which the machine cycle is set. For the control of a glass-forming machine a clockpulse is generated for each degree of rotation and a second pulse train is generated at the rate of one per second. The output of the generator is fed to individual machine section memory units 13 each associated with controls 15 whereby an operator can start-up or shut-down a machine section through an interface 17 comprising solenoid actuated pneumatic valves. Operational commands are stored on a tape and read by a recorder 19 into a central console 21 for possible storage on tape. A section memory unit 13, Fig. 2, receives a train of pulses during a machine cycle at a firing order latch circuit 23 which determines the timing of a controlled section. The latch circuit 23 is controlled by a data link preload shift register 25 which is connected to the central console 21, Fig. 1, and temporarily stores a timing command signal which instructs circuit 23 to couple a reset pulse  signal to a main memory store 27. The main store 27 is initiated by the register 25 and comprises a COS/MOS shift register arrangement; storing section component timing, and a comparator whereby, when a comparison is made, an output signal is provided to a gating circuit 31 for energizing a de-coder and valve drive circuit 33 of the machine section. Start-up and shut-down procedures are determined by memories 35, 37 selected by operator controls 15. A register 39 accumulates data relating to the operating sequences of store 27 and circuit 23 which are fed back to the central console 21, Fig. 1, where the data may be recorded for subsequent repetition of the machine cycle. The machine operating times can be modified during operation, by operation of controls on a console 15.
